FRANCE:
Wild War: my fav mag, old school new school, great articles and interviews, the best coverage of the hardcore Paris scene.

Graff Bombz: Lots of pics from all over France, great if you're looking for inspiration. Too bad the paper they use isn't great quality.

Graff it!: Mostly graffiti, but also rap, other hip-hop related stuff...don't like it as much as the other two.
